Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
The problem has been resolved. Two findings are described below for future reference. The new RPi hw delivered during August 2025 has a MAC address from a new vendor series that is not supported by old runtimes. 4.17.0.0 or above is required. 4.17.0.0 does not pick up the correct architecture during installation and aarch64 has to be manually configured either in the GUI under operations or in /etc/codesyscontrol/CODESYSControl_User.cfg under the [CmpRasPi] section.

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Dear Eschwellinger, Thank you for the response. Does that mean that the license-manager inside the Codesys-IDE does not work with this setup anymore? Because when I use this I get the notification that there is no dongle attached to the device (see picture). And If I insert the license by the deploy tool, can I then redeploy the Codesys virtual control container, or does this erase the license completely?

There seem to be problems with the latest version of raspberry pi os 64bit (I used the lite version). The codesys control runtime crashes after a few seconds. The same runtime works on the raspberry pi image from 2023-10-10 When starting the runtime from the commandline, i get the following error: ooops... this runtime was build for RASPBERRYPI. Hardware version or firmware version not supported! (and yes, I'm running this on a raspberry pi :-)

Post by mputaggio on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

Hello, I couldn't figure what/where the issue was, so I deleted everything from automation server and reinstalled the edge gateway and did the process again. It worked for about a month and then it stopped working again. It presents the same symptom, edge gateway is online but I can't connect to the PLC. Any idea of what could be the issue? Thank you!

Post by wiresplus on Cannot get INT_TO_TIME working ^{CODESYS Forge talk (Post)}
Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

Hello, I need to execute "sudo" commands via CoDeSys 3.5 SP 19 P5 using the "SysProcessExecuteCommand2" function. Commands without sudo are no problem, but as soon as sudo is used in a .sh or a single command, it does not work. Command=AllowAll is entered under "SysProcess" in CODESYSControl.cfg. Nevertheless it does not work. Does anyone know what the problem could be? Greetings, Thomas

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I have not gotten to the bottom of this yet no. I have double check that the variables are correct linked. When online with the program I can see the button and rung going true for the move instruction, yet it does not change. Forcing the bit in the program does change the value in Groov View. I am kind of at a loss here, especially since the other POU(For the pumps) does the same thing fine.

Post by thomasrohnerch on Color Change for Symbols not working ^{CODESYS Forge talk (Post)}
I have some Symbols from the Visualization Toolbox on my Target Visu on the Computer. I tried many Symbols, mainly Arrows. I'm able to control the visibility with condition e.g. "GVL.actual_testvalues.speed <= 0" But I can't do "Toggle color" with boolean GVL.b_toggle_color. Neither "TRUE" nor "FALSE" does change anything. Is this a known issue? I'm using CODESYS V3.5 SP19 Patch 5 + (64-bit). See attached file with more Version-Info. I'm currently using Style 6, Gradient axial 2, 3.5.12.0. I had the same issue with Default 3.5.16.0.

Post by otdeveloper on IEC 61499 ^{CODESYS Forge talk (Post)}
It is being worked on by many companies and its even-driven function blocks seem like a natural evolution of the object oriented industrial programming I have seen Gary Pratt (author of the Book of CODESYS and much more) so expertly implement and explain. I would expect CODESYS to have this front and center on their sights and, if they do not, I would be very interested in learning why.

Post by ferrim on IEC 61499 ^{CODESYS Forge talk (Post)}
IEC 61499 is probably something more complex than what you have correctly said so the prospects are interesting but we cannot ignore that it came out almost 20 years ago and has not won many hearts. I started to explore this world with a PLCnext controller because I love these devices based on RT Linux and Codesys is somehow usable with them but I have made little progress and I feel like inside a nutshell in the middle of the sea ;-) Gary's voluminous and precious book is always on my desk...

(dhumphries) I followed your advice and tried it on Ubuntu Server. Was a good choice. Your material was also very helpful :). Thanks for Your help! I no longer have problems connecting to Ubuntu. However, I still cannot install Virtual PLC. I'm currently getting a missing path message: "C:\Program Files\CODESYS 3.5.19.60\CODESYS\CODESYS Virtual Control for Linux SL\Delivery\virtuallinux\VirtualControlAPI.py." It looks as the package: "CODESYS Virtual Control for Linux SL" was not installed. But, there isn't one in CODESYS Store or I'm doing something incorrectly.

When I try to execute the relative move start command on FB for both the drives it is not working. However, if I add 1ms second delay between the execution of each drive it is working. Also when I change the rung order it is working for the first drive in the rung. what could be the wrong here?

Is there a way that I can create a variable in a GVL that I can control with logic but a user can not put a force on this variable. I have looked at the access rights but this seems to only limit editing the GVL or POU. This variable will only be assigned a value in one POU but it will be used throughout many other POUs.

Post by ara32 on CODESYS 4 Linux: ^{CODESYS Forge talk (Post)}
Hello! I managed to correctly launch CODESYS Developer Studio 3.5.17, almost all functionality works. The only issue remaining is that when connecting to a device and obtaining its public key, the NCryptEncrypt function is called, which is not fully implemented in the DLL source code, resulting in the connection not being established. Currently, the code of this function in the Wine repository looks like this: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG || flags & NCRYPT_PAD_OAEP_FLAG) { FIXME("No padding and oaep padding not supported\n"); return NTE_NOT_SUPPORTED; } if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } The program crashes due to the NCRYPT_PAD_OAEP_FLAG flag. I'm not proficient in C++, but I attempted to add handling myself, and here's the result: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG) { FIXME("No padding not supported\n"); return NTE_NOT_SUPPORTED; } BCRYPT_OAEP_PADDING_INFO oaepInfo = { 0 }; oaepInfo.pszAlgId = BCRYPT_SHA1_ALGORITHM; NTSTATUS status = BCryptEncrypt(key_object->key.bcrypt_key, input, insize, &oaepInfo, NULL, 0, output, outsize, result, flags); if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } Now, when calling the connection, it crashes with the error "bcrypt:BCryptEncrypt flags 0x4 not implemented." Can anyone help with enhancing this functionality or at least point me in the right direction?

Good morning, mecke96. Exactly the same thing happens to me, although I have not done the part of executing a .py file. It only reads the temperature and the counter, but the other values are zero as in your image "no readings". I have tested the MPU6050 device on an Arduino and it works. Could you tell me if you solved it?

Post by food on Beaglebone Black OPC-UA Server ^{CODESYS Forge talk (Post)}
Man, this was a long time ago. I think the problem probably stemmed from not loading the certificates from the client and the server on the server and client respectively in the correct manner. I believe I ended up getting around it just by removing all security on the server. In the end we did not move forward with that architecture so I never had to actually fix it.
